The deformation method of determining the metrological characteristics of variable-force measuring instruments is proposed and examined. The method consists in the excitation of variable forces by a piezoactuator and measurement of the proportional deformation of the elastic calibrated element by a laser interferometer. Unit transfer is shown from the State Primary Standard of units of length, velocity, and acceleration during oscillating motion of a rigid body under GET 58-2018, and the State Primary Standard of force, GET 32-2011. The uncertainty budgets of the determination of metrological characteristics by the known load mass method and the proposed method were compared. A schematic of a measuring installation implementing the proposed method is shown.
